Hall Effect Micro Switch IC Features General Description The APX9132 integrated circuit is an ultra-sensitive, pole independent Hall-effect switch with a latched digital output. A 2.5 volt to 3.5 volt operation and a unique clocking scheme reduce the average operating power requirements, Either a north or south pole of sufficient flux will turn the output on; in the absence of a magnetic field, the output is off. The polarity independence and minimal power requirement allow this device to be easily replaced reed switch for superior for signal conditioning. Advanced CMOS processing is used to take advantage of low-voltage and low-power requirements, SOT-23 package provided a optimized package for most applications. Pin Description

When a magnetic field enters the hall element and exceeds the operate point B OPS (or less than B OPN) the output turns on (output is low). When the magnetic field is below the release point B RPS (or above BRPN), the output turns off (output is high).

A.1 - Nov., 2005 APX9132 www.anpec.com.tw6 OUTPUT OFF BOPN BOPS BRPN BRPS OUTPUT ON MAGNETIC FLUX 0 +B-B MAXOUTPUT VOLTAGE Operation The output of APX9132 switches low (turns on) when in presence of strong flux density facing the marked side of package exceeds the operate point BOPS (or is less than BOPN). After turn-on, the output is capable of sinking up to 1mA and the output voltage is low (turns on). In absence of flux density below the release point BRPS (or increased above BRPN), the APX9132 output switches high (turns off). After turn-off, the output is capable of sourcing up to 1mA and the output voltage is high (turns off). The difference in the magnetic oper- ated and released point is the hysteresis (Bhys) of the device. This built-in hysteresis allows clean switching of the output even in the presence of external me- chanical bouncing vibration and electrical noise. Function Description Awake & Sleep Internal awake & sleep timing block circuit activates the sensor for 180 us and deactivates it for the re- mainder of the period (60 ms). A short “awake” time allows for stabilization prior to the sensor sampling and data latching on the falling edge of the timing pulse. While in sleep cycle the output is latched in its previ- ous state. Chopper Stabilized Technique The chopper stabilized technique cancels the mis- matching of the hall element, the amplifier offset volt- age and temperature sensitive drift by the dynamic offset cancellation and switched capacitor technique. This technique produces devices have an extremely stable Hall output voltage, therefore the magnetic switch points are stable.
Application Information
It is strongly recommended that an external bypass capacitor be connected (in close to the Hall sensor) between the supply and ground of the device to re- duce both external noise and noise generated by the chopper-stabilization technique. This is especially true due to the relatively high impedance of battery supplies. Pole-independent The pole-independent sensing technique allows for operation with either a north or south pole magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same output polarity for either pole in presence.
